Effect of coffee alkaloids and phenolics on egg-laying by the coffee leaf minerLeucoptera coffeella

Bulletin of Entomological Research, 2008
AbstractThe recognized importance of coffee alkaloids and phenolics mediating insect-plant interactions led to the present investigation aiming to test the hypothesis that the phenolics chlorogenic and caffeic acids and the alkaloid caffeine and some of its derivatives present in coffee leaves affect egg-laying by the coffee leaf minerLeucoptera ...
